Panic Attack at Work

Last friday counseling went well.  My counselor taught me a form of questioning with REBT.  It is called chaining, and we got to the root of some of my isses on control too.  At the end, my computer lost connection, so she sent it to me, and I am trying to find a day to reschedule due to my birthday being this friday. At work today, I had a panic attack during a thunderstorm when the lights went out at the shelter.  The room I was almost done with cleaning went pitch black.  I froze, and then in the immediate started to panic.  I had a flashback about the rape in October, and I started to freak.  I had to quickly get my phone out to see some light.   I later called up my co-worker after exiting the room in a panic, and asked him where he was at.  He was making sure the alarm system was alright, and thankfully it was.  The lights then came on about 2 minutes later. I then decided to go back to the room, and still panicky, but unable to get the last bed made, so I called my supervisor.  I either had the choice of calling him or a crisis line, so I called him.  Long story, but he can relate.  He helped me to calm down, and we talked for about 22 minutes.  He wants to speak with me tonight to find out how my day went, and how he can help.   Afterwards, I told me co-worker what my panic attacks are like for me, and he was supportive, and can relate as well.  I love my job, and everyone is wonderful in helping me get through this. I did attempt to try to use positive self-talk and distract myself by making the bed, but it didn't work.  I am trying, but I sure hate my NEIGHBOR. I will keep you updated.
